+Counters
+Counters are used in this ruleset to provide some effects of conquering city:
+* After conquering an city, half of it's population will be unhappy (applies
+for first 5th turns after conquering an city).
+* After conquering an city, 20% of it's population will be unhappy (applies
+for two turns after previous effect).
+* After conquering an city, each tile of this city will produce one less unit
+of each extra: SHIELD,TRADE,FOOD (it applies for first 5th turns after
+conquering).
